AN ODE.

Specification of Ietters Eatent.

Patented Apr. 23, 1918.

To all whom it may concern:

Be it known that I, HENRY R. SWARTLEY, Jr., a citizen of the United States, and a resident of Manhasset, Long Island, in the county of Nassau and State of New York, have invented certain new'and useful Improvements in Anodes, of which the following is a specification.

The invention is an improved anode for water electrolyzers. It is customary to make these electrodestof iron, and in order to protect them from oxidation by the oxygen liberated at their surfaces the general practice is to plate them with nickel. Instead of the electro-deposited surfaces heretofore employed, I propose to provide these anodes with sprayed metal surfaces, that is to say, coatings composed of fine nickel particles rendered molten and impacted on the iron by means of a blast. Metal coatings of this nature are known, but have'not heretofore been applied to anodes, for which such a coating possesses a peculiar advantage. This advantage is the special rough or uneven surface, due to the character of the coating, the structure of which is necessarily different from one formed electrolytically, the effect of such surface being to promote the liberation of the oxygen. It will be understood that the shape of the anode, or whether the electrode is uni-polar or bi-polar, is not material.

The drawing shows an illustrative form t of electrode and indicates the sprayed nickel surface.

What I claim as new is:

An anode having a permanent continuous surface of sprayed nickel.
